Greetings,


Why light affect color of fruit bodies? I can't find any technique answer for it.

Thanks

ABSTRACT:

The following questions regarding the detection of
psychoactive drugs in mushrooms are addressed: At what stage of
the mushroom development can the psychoactive drugs psilocyn
and psilocybin be identified, and what effect does light have on the
growth of these mushrooms.
To answer these questions, Psilocybe
cyanescens Wakefield mushrooms were grown from their spores in
a controlled setting. At various times of their development, samples
were taken and analyzed for psilocyn and psilocybin. Knowing
what stage of development the psychoactive drugs can be identified
may be useful to law enforcement personnel and forensic chemists.
Methanolic extracts of various samples were analyzed by TLC and
by GC/MS. It was determined that the mycelium knot stage of the
mushroom was the earliest stage at which the psychoactive drugs
could be detected. It was observed that light affected the time of development and the appearance of these mushrooms.

Sorry not 100% what you are looking for but..

Effect of Color of Light Emitting Diode on Development of Fruit Body in Hypsizygus marmoreus

Abstract
This study was conducted to identify a suitable color of light for development of the fruit body in Hypsizygus marmoreus. To accomplish this, samples were irradiated with blue (475 nm), green (525 nm), yellow (590 nm), or red (660 nm) light emitting diodes (LEDs) to induce the formation of fruiting bodies after mycelia growth. The diameter and thickness of the pileus and length of stipes in samples subjected to blue LED treatment were similar to those of subjected to fluorescent light (control), and the lengths of the stipes were highest in response to treatment with the red LED and darkness. The commercial yields of plants subjected to blue and green LED treatment were similar to those of the control. In conclusion, cultivation of H. marmoreus coupled with exposure to blue LED is useful for inducing high quality fruit bodies as well as higher levels of ergosterol, DPPH radical scavenging activity, total polyphenol content and reducing power.

Prefacing this by saying I have no idea - I'm just guessing.

My guess is magic mushrooms have melanin pigments in them - UV radiation induces immediate pigment darkening (IPD) by chemical modification of melanin, and possibly spatial redistribution of melanosomes in keratinocytes and melanocytes on skin.

Probably has something to do with that.
